Audio processing method, audio processing device and intelligent earphone

Abstract

The invention provides an audio processing method, an audio processing device and an intelligent earphone, and the method comprises the steps: obtaining environment data transmitted by a sensor, and obtaining a current environment feature vector according to the environment data; obtaining a corresponding current filter parameter from a mapping relationship according to the current environment feature vector, wherein the mapping relationship is a corresponding relationship between the environment feature vector and a filter parameter for audio processing; and controlling the corresponding filter to be enabled according to the current filter parameter. According to the method, calculation is carried out according to the environment data sent by the sensor to obtain the current environment feature vector, the mapping relation between the environment feature vector and the filter parameters in the audio processing process is established in the system, and then the current filter parameters are determined from the mapping relation according to the current environment feature vector, and the filter is enabled to achieve the audio processing; the influence of the environmental characteristics on the audio signals is considered in the audio processing process, and the audio quality is greatly improved after audio processing.

Description

technical field [0001] This application relates to the technical field of audio processing, in particular to an audio processing method, an audio processing device, and a smart earphone. Background technique [0002] In the application process of TWS earphones, the active noise reduction and echo cancellation functions have become the necessary functions of high-end TWS earphone products. In the active noise reduction or echo cancellation algorithm, only the audio signal is processed, ignoring the impact of environmental features on the audio signal, resulting in low audio quality. [0003] Therefore, how to provide a kind of solution that solves above-mentioned technical problem is the problem that those skilled in the art need to solve at present. Contents of the invention [0004] The purpose of this application is to provide an audio processing method, an audio processing device, and a smart earphone. During the audio processing, the influence of the environmental cha...
